I have to agree with Adropac in that I also don't consider Gods, Flashback etc to be pure platformers. For me, a pure platformer (like Mario World) has it's emphasis on the mechanic of jumping skillfully between platforms. This mechanic gradually gets more and more difficult as the game progresses. In a game like Gods or Flashback, this is not what the emphasis of the game is based on. Of course there are 'platforms', but they are more about building an environment for you to explore. The jumping between platforms in Gods is no more difficult at the end of the game than it is at the beginning.

Genres aren't always black and white. There are grey areas.

Doesn't flashback have an automatic jump? I would suppose that makes it less of a platformer than a few have been saying. If flashback is a platformer, than I am a banana.
